Robert Goyer:

The emotional appeal of the flying car is something I don’t understand. Airplanes have been around for a long time, and they’re really good at doing what they do. Cars have been around even longer, and they’re even better at doing what they do, better, to explain, in that cars are supposed to stay firmly planted on the ground instead of fighting with all of its design might to avoid just that fate.
 
 So when I go somewhere, I like to fly there, and then, once I’ve arrived, I just get a car to drive around. There are free or cheap cars just about everywhere I’ve ever flown. And with a couple of good car share apps on my phone, I can always just summon an Uber.
 
 But, for some reason, many find the appeal of a flying car irresistible, to the point where a number of flying cars have been built, though only two of them ever produced, with only a few examples of each, at that. Several others are currently at various stages of development.
